An additional test of posterior cruciate ligament injury is the posterior sag test, where, in contrast to the drawer test, no active force is applied. Rather, the person lies supine with the leg held by another person so that the hip is flexed to 90 degrees and the knee 90 degrees. [ 3 ]
The posterior cruciate ligament (PCL) is a ligament in each knee of humans and various other animals. It works as a counterpart to the anterior cruciate ligament (ACL). It connects the posterior intercondylar area of the tibia to the medial condyle of the femur .
Injuries to the posterolateral corner can be debilitating to the person and require recognition and treatment to avoid long term consequences. [1] Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2]
Typically there is a tear of the anterior cruciate ligament, posterior cruciate ligament, and either the medial collateral ligament or lateral collateral ligament. [3] If the ankle–brachial pressure index is less than 0.9, CT angiography is recommended to detect blood vessel injury. [3] Otherwise repeated physical exams may be sufficient. [2]
Magnetic Resonance Imaging (MRI): [5] [6] The gold standard for diagnosing bucket-handle tears. Key findings on MRI include: Double PCL sign: The displaced meniscal fragment mimics the appearance of a second posterior cruciate ligament (PCL) on sagittal images.
A Philadelphia jury ordered doctors to pay former Eagles special-teams captain Chris Maragos $43.5 million on Monday in a medical malpractice lawsuit related to treatment for a career-ending injury.
It refers to the appearance of a duplicated posterior cruciate ligament, where the displaced fragment of the torn medial meniscus lies parallel and inferior to the PCL, mimicking a second ligament. [1] The double PCL sign has high specificity for meniscal tears when noted on MRI. [2] [3]
Cruciate ligaments. Cruciate ligaments occur in the knee of humans and other bipedal animals and the corresponding stifle of quadrupedal animals, and in the neck, fingers, and foot. The cruciate ligaments of the knee are the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). These ligaments are two strong, rounded bands ...
